An unknown sample of dopamine gave a current of 34.6 nA in an electrochemical analysis. Then 2.00 mL of solution containing 0.0156 M dopamine was mixed with 90.0 mL of unknown, and the mixture was diluted to 100.0 mL in volumetric flask. The signal from the new solution was 58.4 nA. What is the dopamine concentration in the unknown sample?
